Touch Sensitivity?

How is the touch sensitivity on the Nexus One? I ask because my myTouch 3G has serious sensitivity issues towards the edges of the screen. It either won't register a touch or it will only register after pressing harder than normal.
Also, how is the sensitivity compared to an iPhone?

I would say its equal to the iphone if not a little bit better.

Supposed to be a capasitive display, so no need to press at all, touching is enouh.

some time is good, some time is not very responsive, my friend say the weather is too cold, it need to warm up to working. just kidding

Well, the myTouch 3g also has a capacitive touch screen, but mine definitely has sensitivity issues. For instance, when viewing a video, it is extremely hard to jump to different spots using the slider at the bottom of the screen. It just won't respond most of the time.

i knwo what you mean. i had a mytouch 3g and switched to nexus one. I can confirm sensitivity on nexus one is MUCH better, on par with an iphone.

That could easily be the processor not responding, not the screen...

How does the screen feel?(is it glass like as on ipodtouch/phone)
I have the g1 and I hate the plastic feel of the screen. Makes swiping feel odd

In didn't expect to be this impressed to be fair. Only thing so far is I keep missing the spacebar when entering text

the nexus one screen is glass.

I haven't had a single problem hitting menus/keys and I can safely say I love the touchscreen and response from the N1 more than my iPhone & iPhone 3G.

Screen sensitivity doesn't seem to be as good as the 3GS, but it's really so close that you would have to have used an iPhone for 3 years, like me, to really be able to tell the difference. The difference is so small that most likely won't notice it, but you call tell the difference when trying to select links in the browser, without the trackball, for example.

What are capacitive screens really good for?

First things first: I generally like my HD2 - It's fast, has a nice display and a lot of other nice features but the touch screen outright sucks and is bordering on useless. Of course the iphone screen isn't much better but it still beats the HD2 screen hands down.
What's all the fuss about capacitive screens? All I can see is a loss in functionality. I hear their more durable but who cares whether the screen lasts 3 years or 10???? It's nowhere near as precise as any other touch screen device I ever owned. I can't use a stylus for drawing small things or playing most games....try playing crayon physics with this absolute piece of junk...or Warfare Incorporated.
I installed a sensitivity fix cab and it's somewhat usable for day to day stuff but still.....the 4.3" screen is nowhere near as usable as the 3" my X1 had and I could operate that with my finger only quite all right.
Seems like there nothing in capacitive screens other than being iphone-like. Why not have a 4.3" resistive screen? What's the actual downside?

I am and it works just fine for me
There are styluses (styli?) available for cap. screens also though.

The advantige of capacitive touch screens:
Glass can be used. Less vulnerable.
multi touch can be implemented.
more touch sensetive.
The advantige of resistive touch screens:
more accurate without software.
simple styles can be used.
cheap.

Get ready to be flamed for your attitude. Coming onto a forum for fans of a device and calling it an "absolute piece of junk" is a pretty good way to not make friends!
Anyway, I finished Crayon Physics the other day, and had no problems doing so with my fingers. I suggest that the hardware isn't the problem here. Everyone else seems to manage fine.

I'd say the biggest downside of capacitive screens is the absence of multitouch capabilities. I have absolutely no problems operating my phone with it's capacitive screen. So to speak, Windows Mobile 6.x.x isn't really optimized for it anyways, as the HD2 was the first phone with capacitive screen on the platform.
If you wanted to work precise with a stylus then maybe you shouldn't have bought an HD2 in the first place.

No offence but I would say that not being able to play/finish crayon physics deluxe with this peace of jewellery is of course not caused by the screen or the phone. I would search the cause somewhere else.....

The whole benefit of a capacitive screen for me is that I don't have to use a stylus. If I wanted to use a stylus I would have gone for a different phone.
Why did you buy this phone if you wanted to use a stylus? You can however get one, have you tried that first before falling out with the phone? It could fulfill all your needs and then you'll see how good the HD2 is.

I think that it is a matter of habit and getting used to resistive screens in your case. I havent had a resistive screen ever but i played a quite a lot with some and i must say that capacitive is much more interactive, finger friendly and intuitive than resistive so you might just try not to be so stuborn and give it a chance Everytime i try to do something with my girlfriends' resistive samsung and i keep getting stuck with not knowing how hard should I push the screen exactly ... I am not a fan of the resistive and after all it is called TOUCH screen not a Push screen Enjoy your Hd mate !

You can use fingers on resistive touchscreens. These days even resistive touchscreens can have multitouch.
I think the main advantage of capacitive screen is the glass, as was mentioned. Resistive screen must deform under the touching object, which means it wears down.
For phone, capacitive screen is just ok.
For tablet PCs, I'd like to see combination of capacitive screen with electromagnetic stylus (like tablet has) where you could switch the mode.
Capacitive screen is good for fast controls, but if you draw with stylus, you don't want the screen to react on random touches.
For example iPad has rather thick borders around the screen .. because you have to hold it somehow without actually touching the screen.

A capacitive screen makes our screen a real touch screen instead of 'tap screen'.

I don't think so. Resistive is much more sensitive and precise. Pen stroke input used to be the reason PPC stuck to resistive input.
Being an HD2 fan doesn't mean a capacitive fan. Capacitive is the reason that I nearly bought an Omnia II instead of HD2. For me, it is something to hate.
With resistive, I don't mind carrying around a stylus when it means I can do precision work. And I can still use my fingers when I need to.
Now that we have WVGA, I believe now that we can sacrifice screen estate and use huge UIs so that capacitive screen can survive. But that means old applications written for resistive screens (including WM6.1 dialogues) usually have too small UIs for use on HD2.

Alex, That the Capacitive touch is more sensetive is an advantige, with the interface or software you can decrese the sensetivety. On resistive touch screens it is technicaly inposible to get the sensetivety as high as on capacitive.
It is posible to make resistive touch screens multitouch. only that takes a lot of software to calculate positions of pressing.
The techniek is very different between both. therefore you love it or you don't. some get used to it, some don't. It is all personal. There are even people who love the small keyboards. And even my wife loves only the number keys on the normal simple phones since she uses the dictionairy. And I have to say, She is faster writing a sms than me.
So everyone should use whatever they like. Every option has it's advantiges.

I should have been more specific: The junk I'm referring to is the screen and NOT the device. Like I said, I like the device but IMHO all the 'advantages' of capacitive don't make up for its downsides.
Just to address some of the comments:
Resistive screens CAN be touch operated without a stylus
They do NOT break down all the time
AFAIK they CAN support multitouch
Maybe it's just the crappy implementation of capacitive that HTC has done. The Iphone screen does not seem to suffer from all the issues the HD2 has:

The stylus for capacitive screens is a joke. Come on, do they have to be that fat and ugly? Is there really no way to have a small, pointy, conductive stylus?
Are capacitive screen really a requirement for WM7?

Hahahahahaha!!! John is right. Better be careful what you post on this forum.

I say put your fingers on a strict diet! Enroll them in a exercise regime until you can use your "piece of junk" effectively.

Well, for me the #1 reason for me to get an HD2 IS the capacitive screen.
I've had many many resistive screen devices (1 old pocketpc, 4 HTC phones, 2 touch-enabled UMPCs), and I'm tired of having to use my nail to press on that screen. It's perfectly fine on old-style UIs that rely on clicks only, but for the "new" flick, scroll, tap, pinch, rotate, capacitive is just the way to go.
Still getting mad when I tap my Kaiser's screen with my finger (not the nail) and it thinks I want to scroll, and goes 2 pages down... only works fine with something sharp, whatever the settings/tweaks.

capacitive is a reason to buy for me: it is what made the HD2 stand out for me. I will never go back to resistive technology.
I must say though that in my opinion the iPhone display is of a superior quality, not in terms of pixel count, but certainly in terms of its accuracy, sensitivity and reliability. it is simply a lot easier to tap out words on the iPhone than on the HD2. It also responds better to cold (if I go out in the winter breeze I sometimes find my HD2 starts pressing keys and moving the screen about of its own accord).

Low screen sensitivity

Just bought a new Nexus one to use while I'm overseas (used an EVO 4G back in the states) and one of the first things I noticed was the touch screen seems considerally less sensitive than the one on my EVO. I find myself having to hit the screen multiple times because the first touch didn't register often. This applies to the capacitive buttons on the bottom of the screen as well.
Has anyway used a Nexus One vs. another phone and noticed its screen being slightly less sensitive. I have the SLCD version by the way but I think it uses the same sensor as the AMOLED so I'm not sure that makes a difference.

The N1 has a crap digitizer. It's one of it's weak points sadly.

Hit the capacitive buttons slightly above where you think they are. Works every time...

+1 especially its alignment is really inaccurate when using the multi touch function

It is kinda rough. But not too bad. Maybe just a bit worse then my HD2.

S Memo works fine with my finger

It's a lot easier to access and far more convenient. Easier to control. I can sketch and draw far better. I can write across whatever with ease. It turns into an eraser at the touch of a button and I can work in all the colors, line variations and settings available for the stylus. I can take screen shots by hitting power and home buttons at the same time. If I need text I type. My handwriting with the stylus is difficult to read and takes up far too much space. So, finger it is.

I understand the s-pen on the Note does not have to be used as it will work well with fingers. But I'm surprised that you can draw and write better with your finger than the s-pen.

I was surprised as well. Especially the drawing and sketching. It's like using a piece of charcoal.

What about 'Pressure Sensitivity', does it work with the finger?
It is supposed to work with the Pen but I'm a little skeptical that works correctly even though the screen has wacom tech underneath.

Pressure sensitivity does not work with your fingers. It acts as if you are pressing very lightly with your stylus. Pressure sensitivity works just fine with the stylus but the slight lag (maybe .1 second) makes drawing lightly tricky.
(post edit) : i was wrong. I was touching nearly light enough.

Thanks Guys,
Interesting though as we have conflicting answers here.... It must be down to the application being used.

Let me reclarify my vague edit - the screen is pressure sensitive with your finger. But the screen is very sensitive and to register a 'light' touch you barely touch it at all. I could touch the tip of a needle with more force.

dots on screen ?

i was looking on one device on the bestbuy store and when i was
deflecting the device i could notice the a matrix of spots/dots on screen
that never disappear only if i hold the device in some angle it would be not noticeable...
so i wanted to ask:
1. Am I the only one that saw that?!
2. if i will put a protect cover on screen it will make this dots/spots not seen?

Perfectly normal. The glass is supposed to be Gorilla, so I wouldn't even bother with a protector.
Sent from my Kindle Fire using xda premium

why is that normal ?
i haven't saw that on a PlayBook or a iPad or a Samsubg tab...
so why is this normal ?!

That's the grid for the capacitive touch sensor. On some devices it's more visible than others. I guess Amazon is using one of the more visible ones on the Fire.

Since this is bothering me very much, do you think if i would apply over it a protector it would be non-visible ?

Eh I can't see it on mine at all. Maybe It's just the display.

I doubt it, but you can try. FWIW, I can see the dots, but they only appear at an angle with certain glare on the screen. Doesn't bother me.

It's normal. You most likely noticed it due to light reflecting on it at a certain angle. My ipad had those, and my touchpad has them. I don't notice it unless the screen is off and its held at an off angle with a good amount of light reflecting off the surface. You don't notice it while it's on.

This was VERY visible on my Nexus One, but isn't on my Sensation. It's back on the Kindle, but you only notice it when.the screen is off. It depends on the display, and I think the more reflective the screen, the less you see.
Sent from my Sensation using XDA App

It has both dots and also a grid matrix. You can see it on every one, just have to turn the unit *just so* to see it.

My understanding from a post on Amazon about the device is that its not a capacitve or resistive touch screen but an infrared touch screen.
Confirmed myself that it is not capacitive as you can touch it with anything and it responds, where my iphone and Captivate do not.
Food for thought. Has anyone else heard of an IR touchscreen before?

Ive always been able to see the dots on every touch device I've owned. Just requires the right angle and light.

Yeah, they're just rarely used, because the technology has only been reasonably cheap/simple for a few years (iirc), whereas capacitative and resistant touchscreens have been around for much, much longer.
Also, touching the screen with a pen lid doesn't do anything for me. You sure it works with *anything*? I got it to work with a piece of moleskin, though, so... maybe it's just certain things?

Was just able to unlock using a paper napkin folded three times to make sure it wasn't skin touching anywhere. Tried with my leather wallet and it didn't react. Very strange. Also tried a microfiber cleaning cloth, didn't react on my iphone or captivate but worked on my fire. Wheird.

The Kindle with the IR touch screen is the Kindle Touch, which uses the IR touch screen because capacitive touch screens aren't available for the E-Ink screen yet. IR touch screens work by shooting IR lasers across the screen in a grid format, so a touch would trip IR lasers, and which lasers are tripped can be used to calculate where the touch is in. That's what they use on the Nook Simple Touch, too. I remember my old car built-in GPS was an IR touch screen. You could trick it by blocking the IR receivers.
Nowadays, most LED touch screens are capacitive, which is what's on the Kindle Fire (the reason why there's dots on the screen - I think they're the sensors that measure the capacitance to calculate the location of the touch).
